In fairness to Lord of Rigel, I don't find it a bug-filled mess or anything. I just find it...kind of boring right now.
Which makes me sad, because design-wise, I like what the game is doing. it's just somehow falling short in the implementation, and/or perhaps presentation.
Normally I'd jump on a game like this but I'm just too tired of all these games that pop up sounding great and end up being an unfinished, bug filled mess.
Just from glancing at my Steam library (I'm sure there's a lot more titles in there):
Apollo4x
Astra Exodus
Dawn of Andromeda
Falling Stars: War of Empires
Galactic Inheritors
Galactic Ruler
Pax Nova
Predestination
I think I've been permanently cured of Day One Purchase Syndrome.

Man, you suck at picking 4x games, if that's your list (I only own 2 of those). But we'll set aside your questionable tastes for the time being.
I do get what you're saying, though. For as admittedly pumped as I get for the majority of 4x games when they're announced, even I rarely end up buying them on release day (or even release week). The odds are too high that they don't pan out.
